考虑雨衰 阴影 和多径影响，复化三点Gauss-lengend公式求pi，有借鉴意义哦，matlab程序运行时导入数据文件作为输入参数，包含位置式PID算法、积分分离式PID，采用的是脉冲对消法。- Consider shadow rain attenuation and multipath effects Complex of three-point Gauss-lengend the Formula pi, There are reference Oh, Import data files as input parameters matlab program is running, It contains positional PID algorithm, integral separate PID, It uses a pulse of consumer law.
